Cut broken stems. It looks best to support plants before they get to the flopping and damaged point, so next year use low fences or a stake and string support system tucked in close under the branches so that as they leaf out and grow the supports are hidden. Mine is wedged in between a large rhododendron and a spirea that help prop it up, so it looks OK even after several pounding rains and a hailstorm with 1/2" hail. You can try adding something now, but IME it usually ends up looking like something as been created after there was an issue - perhaps just my clumsiness.

I also am sold on the incredibal. After rain and wind, it doesn't droop. It's also in all day sun.

Thanks, Candeelyn! Incredibal "might" droop a little the very first year, but haven't had any problems at all after that. 100% stronger stems than Annabelle. Love mine!

I let mine spill forward, and the two shrubs prop it up from the sides.
